Abstract
The total synthesis and antileishmanial activity of deoxyalpinoid B is reported via a cationic gold-catalyzed Meyer-Schuster rearrangement. The activity of deoxyalpinoid B and a known inducer of oxidative stress, sulforaphane, against Leishmania donovani and Leishmania infantatum are both reported for the first time. Both compounds exhibit potent antileishmanial activity against both species. We hypothesize that the activation of intracellular oxidative stress is a key molecular response for the inhibition of Leishmania.
